Struggling a bit with this one. We are using BES 4.1 with Exchange 2003 SP2.
User has a 7250.

I have a user who's primary email is and another alias which is .

The user only wants his alias mail forwarded to the Blackberry, but if I setup filtering for the the primary Exchange address no mail gets through to the blackberry. I seem to be able to filter out the alias without issue.

Is there a solution I am missing or a work around that someone has discovered.

What if you setup a filter on the BB and use the 'Sent to:' option (with his email address) the and set that action to NOT forward to the handheld ... then make sure the "if no filters apply, send email to handheld" is set to Yes?

Alternatively you could set the alias to forward to a BIS (BlackBerry Internet Service) account
